I bought this mattress for my severely Autistic son who is non-verbal and sleeps very restlessly.   I must say that he is 18, but has developmental delay and has been sleeping like an angel in his new queen size mattress.   From the moment that he saw it, he jumped right on top and didnt want to get out.  It offers great back support and at the same time,it allows your body to adjust to the perfect posture.  It was worth the wait.  I highly recommend it.
